Math Practice TEAS Test

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS/BODMAS). First, we calculate the multiplication and division from left to right: 6 + 7 = 13, 13 - 4 = 9, 9 * 2 = 18. So, the correct answer is 18. Choice A is incorrect because it is the result of multiplying all the numbers together. Choice C is incorrect as it is the result of adding all the numbers together. Choice D is incorrect as it is the result of adding the first two numbers and then multiplying by the last two numbers.

Correct Answer: A

Rationale: The correct answer is A: This is a linear association with a positive correlation. This scatterplot shows a clear pattern where the data points form a straight line that slopes upward from left to right, indicating a positive correlation. Positive correlation means that as one variable increases, the other variable also tends to increase. In this case, the data points are clustered around the line, showing a strong linear relationship. Choices B, C, and D are incorrect because the scatterplot does not exhibit a negative correlation, nonlinear association, or no association. The linear pattern with a positive slope in the scatterplot supports the selection of choice A as the best description of the data.

Correct Answer: D

Rationale: To find the sale price, first calculate the discount amount: 30% of $472 = 0.30 * 472 = $141.60. Subtract the discount from the original price: $472 - $141.60 = $330.40. Therefore, the correct answer is D. Choice A is incorrect as it is the calculated discount amount, not the sale price. Choice B is incorrect as it does not consider the discount. Choice C is incorrect as it is the original price minus the discount, not the final sale price.

Correct Answer: A

Rationale: The correct answer is A: Ranges. Histograms display continuous data in intervals or ranges, showing the frequency of data points within each range. This is a key feature that distinguishes histograms from bar graphs, which depict discrete categories. Ranges are crucial in histograms to visualize the distribution of data across different intervals, allowing for a better understanding of the data's spread and frequency distribution. Choices B, C, and D are incorrect as bar graphs also utilize categories, labels, and percentages in their presentation of data, respectively.

Correct Answer: A

Rationale: To convert kilograms to pounds, we use the conversion factor 1 kg = 2.20462 lbs. So, to find Stella's weight in pounds, we multiply her weight in kilograms (56) by the conversion factor: 56 kg * 2.20462 lbs/kg ≈ 123.46 lbs. Therefore, Stella's approximate weight in pounds is 123 pounds. Choice B (110 pounds) is incorrect as it underestimates the conversion. Choice C (156 pounds) and D (137 pounds) overestimate the conversion.
